Patented Oct. 15, 1929 a v warez PATENT? OFFICE WELLINGTON I. VCLEMENTS, or NORFOLK, VIRGINIA WIND AND RAIN DEFLECTOB FOR WINDOWS Application filed February 1, 1928. Serial No. 251,141.

This invention relates to window ventilators, and has for one of its objects to provide a novel, simple and inexpensive device of this character which shall be adapted to be secured across an open window in a manner to cause the air to enter the room in an upward or downward direction, whereby to permit the ventilation of the room without subjecting its occupant or occupants to drafts.

A further object of the invention is to provide a ventilator of the character stated which shall be adapted to occupy suchposition across the open window as to prevent 1 rain from entering the room.

A further object of the invention is to provide a ventilator of the characterstated which may be readily adjusted to control the amount of air entering the room and to vary the angle at, which the air enters the room, as

conditions may require.

WVith the foregoingv and other objects in view, the nature of which will appear as the description proceeds, the invention consists in the construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, wherein:

Figure 1 is an elevational view illustratused when it is desired to cause the air to travel upwardly as it enters the room,

Figure 2' is a sectional view taken on the vertical plane indicated by the line 2--2 of Figure 1,

Figure 3 is a sectional view taken on the horizontal plane indicated by the line 3-3 of Figure 1,

Figure 7 is a vi ewsimilar to Figure 6 ing the manner'in which the ventilator is retaining elements maybe in the form of 8 illustrating the application of a modified form of the ventilator to cause the air to travel downwardly as it enters the room and to prevent'rain' from entering the room, and Figure 8 is a view inside elevation of a portion of a slightly modified form of the attaching elements.

Referring in detail to the drawings, 1 designates the sides, 2' the sill, 3 the lower sash and 4 the screen of a window.

The ventilator comprises an elongated rectangular panel or shield 5 which is flexible and made preferably from water-proof fabric or other suitable material. The shield 5 may consist of one or more layers or plies of the material, and it is provided with end "pockets 6 and a central pocket 7. The pockets 6 and 7 extend vertically or transversely of the shield 5, and are closed at their lower ends and open at their upper ends. The pockets 6 are spaced inwardly from the ends of the shield 5, and those portions of the shield located outwardly beyond these pockets constitute flaps 8, the purpose of which will presently appear. Attaching members 9 which are longer than the height of the shield 5, are connected to the shield by having their lower portions removably positioned in the pockets 6. The members 9 are freely flexible and elastic, they are as shown, strips made preferably from spring steel, and they.

are provided at their upper ends with spring retaining, elements formed by bending the upper terminal portions of the, members. The

closed loops, as shown at 10, or in theform of open loops as shown at 10 The free ends of the loops 10 are secured to the members 9 by clips 11. The members 9 are provided between the shield 5 and the-retaining elements with sleeves 13 'which are made preferably from rubber and provided with roughened surfaces 14. The sleeves 13 may be mounted on the members 9 for adjustment in the direction of the length thereof, and their frictional contact with the strips is such as to hold them in adjusted position. The sleeves 13 may be, if desired, se-

cured to the members 9 in a manner. to hold them against movement with respect thereto.

In practice, when it is desired to cause the air to be deflected or travel upwardly as it enters the room, the ventilator is applied to the window as shown in Figures 1, 2 and 3. In this application of the ventilator, the shield 5 extends across the window with its lower edge in contact with the sill 2 and with the flaps 8 in contact with the inner and side faces of the sides 1. The members 9 extend inwardly and outwardly beyond the sash 3 and contact with the lower side of the sash and with the sill 2. The retaining elements are adapted to be positioned in the upper sash receiving grooves of the window, and as they are elastic they contact with the inner and outer walls of the grooves in such manner as to prevent a strong wind from displacing the ventilator. It is not necessary to position the retaining elements in the sash groove when only light winds are blowing, the cont-act between the sleeves 13 and sash 3 being suflicient' to hold the ventilator in place. The sleeves 13 may be positioned, if desired, in contact with the lower outer corner of the sash 3. The shield 5 curves upwardly and inwardly, and due thereto the air will (ill 5 conditions may require.

be deflected or caused to travel upwardly as it enters the room. The curvature of the shield 5 may be increased by lowering the sash 3 and decreased by raising the sash, and due thereto the amount of air and the upward inclination thereof may be varied as When the window is provided with a screen, the retaining elements may be placed againstthe frame of the screen as shown. are slidably related to the part or parts with which they contact, and due thereto the members 9 may be readily bent to impart the desired curvature to the shield 5. The sleeves 1.3 may be omitted, as the ventilator will remain in place without their use. They do however materially assist in maintaining the ventilator in place.

When it is desired to cause the air to travel downwardly as it enters the room, the ven: tilator is applied in the manner shown in Figure 6. In this application of the ventilator, the upper edge of the shield 5 contacts with the lower edge of the sash 3, the members 9 contact with the sill 2, and the attaching elements may be positioned in the upper sash receiving grooves or in contact with the screen. The lower edge of the shield 5 is spaced above the sill 2, and the air enters the room between the shield and sill. The

size of the opening between the sill 2 and the lower edge of the shield 5 and the curvature of the shield may be varied by raising and lowering the sash 3, and due thereto the amount of air and the downward angle at which it enters the room may be regulatedv a e n t may r q e The ventilator The retaining elements may be provided, as shown in Figure 7, with an auxiliary shield 5 which is carried by the strips 9 and contacts with the sill 2. This shield has its upper edge spaced from the lower edge of the main shield 5 to provide an opening for the entrance of the air, and it serves to prevent water from entering. the room.' The auxiliary shield 5 may be slidably associated with the members 9 to permit it to be adjusted with respect to the main shield 5 whenever it is desired to vary the size of the opening between the shields.

The flaps'S serve to prevent air and water from entering the roombetween the ends of the shield 5 and the sides 1 of the window. As the shield is provided with the central pocket 7, oneof the strips 9 maybe placed in this pocket and the shield folded upon itself. This reduces the length of the shield and adapts the ventilator for use at one side of the open window. When theventilator is used in this manner, the air at one side of the open window enters the room in a hori zontal direction and the air entering the room I at the other side of the window is deflected either upwardly or downwardly. It should be understood that the dr'awings are merely illustrative and do not pretend.

to give exact proportions. Furthermore, said drawings are illustrativeof preferred constructions, it being my expectationthat various changes and modifications may be made without departing from' the spirit and scope 2. A ventilator comprising a flexible shield.

In testimony whereof I affix my signature.
